Stainless Steel AISI 304L Fasteners

AISI 304L Equivalent Grades

AISI 4130 Bolts

Stainless Steel Alloy SS 304L fasteners have low carbon content as compared to SS 304 fasteners.Stainless steel 304l fasteners are usually cold formed as per ASTM A192/A194, F593/F594, BS EN ISO 3506-1/3506-2 specifications. 304L fasteners are preferred for forming fasteners due to their low carbon content and high forming properties. AISI 304 fasteners are available in all types of bolts, screws, stud bolts, threaded rods, nuts, washers and custom bolting parts, in metric and imperial sizes with coarse and fine threads.

304L Stainless Steel is a low carbon variant of 304 austenitic stainless steel, alternatively known by its grade equivalent AISI 304L, DIN 1.4306 & UNS S30403. 304L is often used where welding compatibility of 304 is less than required, along with slighly high corrosion resistance is expected. Due to low carbon content, SS 304L has higher forming properties and are preferred choice for manufacturing cold forged fasteners.
